3. 使用pandas的drop_duplicates方法删除DataFrame中的重复行 你可以使用以下代码来删除基于列A和列B的重复行: python import pandas as pd # 假设df是你的DataFrame # 创建一个示例DataFrame data = {'A': [1, 2, 2, 3, 3, 3], 'B': [4, 5, 5, 6, 7, 7], 'C': [10, 20, 30, 40, 5...
# 检测重复的行duplicate_rows=df.duplicated()print(duplicate_rows) 1. 2. 3. 输出结果如下所示: 0 False 1 False 2 True 3 False 4 True dtype: bool 1. 2. 3. 4. 5. 6. 从输出结果可以看出,第3行和第5行是重复的行。 删除重复的行 一旦检测出重复的行,我们就可以使用drop_duplicates()方法...
DataFrame.drop_duplicates(self, subset=None, keep='first', inplace=False) Return DataFrame with duplicate rows removed, optiona
Drop Duplicate Columns of Pandas Keep = First You can useDataFrame.duplicated() without any arguments todrop columnswith the same values on all columns. It takes default valuessubset=Noneandkeep=‘first’. The below example returns four columns after removing duplicate columns in our DataFrame. #...

This function is used to remove the duplicate rows from a DataFrame. DataFrame.drop_duplicates(subset=None, keep='first', inplace=False, ignore_index=False) Parameters: subset: By default, if the rows have the same values in all the columns, they are considered duplicates. This parameter is...
drop_duplicates()is used to remove duplicate rows from a DataFrame. You can specify which columns to check for duplicates using thesubsetparameter. By default,drop_duplicates()keeps the first occurrence of each duplicate row, but you can change this behavior with thekeepparameter (e.g., ‘last...
DataFrame.drop_duplicates([subset, keep, …]) Return DataFrame with duplicate rows removed, optionally only DataFrame.duplicated([subset, keep]) Return boolean Series denoting duplicate rows, optionally only DataFrame.equals(other) 两个数据框是否相同 ...
pandas.DataFrame.drop_duplicates()函数 官方文档给出的这个函数的作用是ReturnDataFramewith duplicate rows removed, optionally only considering certain columns.也就是删除重复的行之后返回一个DataFrame,可以选择只考虑某些列。 函数原型如下:DataFrame.drop_duplicates(subset=None,keep ...
